GoKawiilModder develops auxiliary 8-pin board to fix RTX 5090 connector melting
Reddit user DallasGrave, reportedly affiliated with cooling company Grave PC, detailed a mod that solders a pickup PCB to the RTX 5090's 12VHPWR header and routes power through an added dual eight-pin board, spreading current across three cable sets. The user says a card modified this way ran at 550W for 48 hours with cable temperatures staying under 40°C, and plans to offer the conversion as a paid service with warranty, with a PNY-branded version also in the works.
